This is the configuration. Further, the control device 13 includes a load drive circuit 20 composed of electronic parts such as a triac and a relay for driving a load, and a microcomputer 21 having a RAM, a ROM such as a counter, a timer, and a clock function. Yes. Here, the operation of the microcomputer 21 is carried out in the form of a microcomputer program in which the counter, timer, clock function, RAM, and ROM in the microcomputer cooperate.

  As shown in FIG. 3, the water level detection means 19 of the dehumidifying device includes magnetic sensors 19 a, 19 b, 19 c, 19 d, and 19 e for detecting the water level inside the main body 1. 7 includes a float 19g that moves in the vertical direction in the cavity of the guide 19f due to a change in the water level.

  As shown in FIG. 4, a magnet 19h for operating the magnetic sensor is attached to the float 19g so as to be on the surface on which the magnetic sensor is attached. The shape of the float 19g is chamfered at the four corners of the portion that hits the corner of the guide 19f so that the float 19g moves smoothly in the vertical direction in the cavity of the guide 19f, and the float 19g rotates in the horizontal direction.
